ELECTRIC SIGNAL.

no. 885,519. Specification of Letters Patent. Patented April 21, 1908.

Application filed Novemberll, 1907. I Serial No. 401,585:

To all whom-it may concern.

Be it known that I, JOHN REBAR, a citizen of the United States ofAmerica, residing at Smithdale, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Electric Signals, .of whichthe following is a specification, reference being had thereinto the accom anying drawingr T is invention relates to electric signals for railway trains, and its primary object is, to provide a simple and inexpensive signaling device whereby the engineer may be communicated with from convenient points throughout the length of the train.

- A further object of the invention is to provide. signaling apparatus comprising resiliently supported contacts preferably carried a by the car couplers, and adapted to have a wiping frictional contact: I I

he construction of the improvementwill be fully described hereinafter in connection with the accompanying drawing which forms "a part of this specification, and its novel features will be set forth. in the appended claims.

. In the drawing: Figure 1 is a diagram- -matic view of a railway train equi ed with my im roved signaling. apparatus, ig. 2 is a top an view of two interlocked coupler heads, with .my improved disk contacts secured-thereto by resilientarms, Fig. 3 is a front elevation of the coupler-heads with confltactdisks secured at the sides ofthe same, and Fig.4 is a vertical transverse section through one of the'co'ntactdisks and its supporting s ring.

The re erence numeral 1 designates asignal bell located in the locomotive cab, a battery 5 2 being also located in the cab or at some convenient point.

The conductor 3 from one side of the bat.-

teryis electrically connected to a disk 4 mounted upon a bolt 5 extending through an -o eningin the outer end of a curved spring 6, t e inner end of which is secured to the coup- "ler'head 7.. The spring 6 is insulated'i'rom the bolt 5 anddisk 4,'and as the conductor wire 3 is-attached to the bolt the circuit is through the bolt and disk. The disk 1 bears against a similar disk 8 supported by the adjacent coupler head 9 by a curved spring 10 and this disk is connected by a Wire 11 with a similar disk 12- atfthe o posite end of the car and soon throughouttl e length of the train. 65 The conductor 13 from the opposite side of the battery is connected to a disk 1 d su ported at tie opposite side of the coupler cad 7 by a spring 1.5, and contacts with a disk 16 secured to thecoupler head 9 by a curved spring-17. The disk 16 is electrically connected to a similar disk at the opposite end of v the car, each car of the train being )rovided with two pair of contact disks at eac end arranged at the sides of the coupler heads as shown, said disks and their connecting wires and. the wires 3 and 13 constituting the bat tery circuit which is normally open. To close this circuit and ring the hell I employ a plurality of circuit closers 18 located preferably one at each end of the car and by means of these circuit closers which may be push buttons, or switches of any approved form, the battery circuit may be closed at the various points indicated in the diagram.

It will be noted that the several disks employed are pressed out centrally rovidin a concavo-convex hub 19, and a at circu ar bearing surface 20 to insure a good contactbetween the oppositely disposed disks. The spring arms afford a resilient support for the contact disks and permit the meeting faces thereof to rub against each other With-8, wiping contact, which not only insures a good electrical contact, but also prevents corrosion of the disks.

If preferred the one pair of disks as 14 and 16, may be omitted, and the return current to the battery may be through the'couplers and other metallic elements below the 'car body.

I would have it understood that the invention also includes all such othermodifications and variations in the details of construction as may fall within the terms and scope of the claims.

Having'now described my. invention what I claim as new, is:-

1. A railway train signal system, comprising a signal bell, a battery, a'circu'it from the battery to each car of the train, contactsca'rlied on opposite sides of the couplers of said cars, each contact comprising a contact-disk,

a curved spring arm having its inner end attached to the coupler and the said disk attachedto its outer end and insulated therefrom, the said disks being included in said circuit, and circuit.closers on each car, substantially as described.

2. In a railwa train signaling system, the

combination wit a signal bell, a battery, and

a circuitfrom the batteryofeach car of the .wires connected direct thereto, and circuit. train,-ofco'n'tact s carried on ogposite sides of closers in each car for said circuit. 10 the couplers of "-said cars, eac contact com- In testimony whereof I afi'lx my signature prisin' a disk'having a projecting hub, a inthe presence of two witnesses.
